When connecting rod 5 or 6 is fixed to the end of brush fixed axis 52; In the position mark 55 of three positions of fixed screw 57 on the outer peripheral edges that are arranged at brush fixed axis 52 one be selected and with state that alignment mark 56 aligns under, the fastening screwed hole 58 that is fixed to.Under the state of aligned in position, the brush 53 that is arranged in the row who is associated with the position mark that is aligned in alignment mark 56 55 is in the face of dirt collection plate 32.Therefore, the brush of selecting through the aligned in position between mark 55 and 56 53 comes in contact with dirt collection plate 32, and is as shown in Figure 9.Position mark 55, alignment mark 56, fixed screw 57 and screwed hole 58 constitute selected cell.
In above-mentioned structure, brush weares and teares because of the operation of electrostatic precipitator gradually.Yet brush 53 comes in contact through bias unit and dirt collection plate 32 with suitable pressure under brush wearing and tearing less state, has therefore kept the dust cleaning performance.Yet, if brush serious wear and length shortens is difficult to keep cleaning performance through bias unit.In this case, be necessary to replace brush.Yet in the present embodiment, through selecting a unworn brush row and being arranged at the brush that has worn and torn the row's in the many rows brush 53 on the outer peripheral edges of brush fixed axis 52 mode with its replacement, the dust cleaning performance is able to continue.
To use accompanying drawing to describe the replacement work of brush below.Figure 12 is provided with the key diagram of brush replacement work among the 5th embodiment of two row's brushes at each brush fixed axis 52 place.Shown in Figure 12 A, wearing and tearing take place in brush row who wherein is positioned at dirt collection plate 32 left sides and length shortens, unclamp set bolt 57 so that connecting rod 5 with 6 and brush fixed axis 52 can rotate.Secondly, shown in Figure 12 B, use a tool (not shown) that brush fixed axis 52 is rotated along the direction of arrow (clockwise), so that the position mark 55 that is arranged on the outer peripheral edges of brush fixed axis 52 rotates.Be further rotated selecting and to separate 180 ° brush with wearing and tearing brush row and arrange the position mark 55 that is associated and make under the position mark of selecting 55 and the state that alignment mark 56 aligns at brush fixed axis 52, fastening set bolt 57 is to be fixed to brush fixed axis 52 with connecting rod 5 or 6.Under this state, shown in Figure 12 C, the not wearing and tearing brush selected row is biased unit biasing coming in contact with dirt collection plate 32, thereby can keep predetermined dust cleaning performance through the dirt collection electrode.
Above-described is the situation of the brush generation wearing and tearing in dirt collection plate 32 left sides.Yet, even the brush on the right side takes place under the situation of wearing and tearing, also can be through similar manner replacement brush.In addition, that kind is provided with under the situation of three row's brushes in as the 6th embodiment, can replace the brush of wearing and tearing through selecting the row in other two row's brushes in order.Therefore, the dust cleaning performance can be kept than the length of the 5th embodiment.
In the present embodiment in order to select and replace brush row; Be provided with the selected cell that comprises said a plurality of position mark and alignment mark; Said a plurality of position mark is arranged on the outer peripheral edges of brush fixed axis, and said alignment mark aligns with position mark and is arranged on the bias unit place.Therefore, can under the situation of not opening housing 12, easily and accurately select brush to be replaced.In addition, because the length of brush of wearing and tearing shortens, so even brush fixed axis 52 is along turning clockwise shown in the direction of arrow among Figure 12 A, brush can not hinder the dirt collection plate 32 that moves up yet.Therefore, even when dirt collection plate 32 moves, also can carry out replacement work, thereby can under the situation of the operation that does not stop electrostatic precipitator, replace brush.
